Zosefera zosindikizira (zomwe nthawi zina zimatchedwa Plate-and-Frame Filter press) zomwe zimalongosola kalembedwe kazosefera zomwe zinapangidwa kuyambira zaka za m'ma 1800 kupita m'tsogolo poyambira dongo. Zosefera zambiri masiku ano zimatchedwa "chosindikizira cham'chipinda", "Chosindikizira cha membrane", kapena "Sefa ya Membrane Plate". Njira zambiri m'mafakitale azakudya, mankhwala kapena mankhwala amapanga zinthu kuchokera ku kuyimitsidwa kolimba kwamadzi kapena slurries. Zosakanizazi zimakhala ngati matope othamanga kapena kugwedeza mkaka. Zolimba mwa izo sizimasungunuka mumadzimadzi, koma zimatengedwa mmenemo. Zosindikizira zosefera zimalekanitsa zolimba ku zakumwa kuti gawo lothandiza lithe kukonzedwa, kupakidwa kapena kuperekedwa ku sitepe yotsatira.
Zosindikizira zosefera nthawi zambiri zimagwira ntchito mwanjira ya "batch". Ma mbalewo amangiriridwa palimodzi, kenako mpope imayamba kudyetsa slurry mu makina osindikizira kuti amalize kusefa ndikupanga gulu la zinthu zolimba zosefedwa, zomwe zimatchedwa keke ya fyuluta. Mulu wa mbale umatsegulidwa, zolimba zimachotsedwa, ndipo mulu wa mbale umamangidwanso ndipo kusefa kumabwerezedwa.

Makina osindikizira amagwiritsira ntchito mphamvu yowonjezereka ya mpope kuti apititse patsogolo kusefa ndikupanga keke yomaliza ya fyuluta yokhala ndi madzi osakwana 65%. Izi zimakhala zogwira mtima kwambiri kuposa kusefera nthawi zonse chifukwa cha kuchuluka kwa kusefera komwe kumagwiritsidwa ntchito ndi mpope yomwe imatha kufika paliponse pakati pa 50-200 PSI. Makina osindikizira a fyuluta amakhala ndi zipinda zosefera zomwe zimapangidwa pakati pa mbale zosefera, zamakona anayi kapena zozungulira zomwe zimathandizidwa pachitsulo. chimango. Zipinda zosefera zikamangika, makina osindikizira amadzazidwa ndi slurry. Ma mbale omwe ali pa makina osindikizira amamangiriridwa pamodzi ndi nkhosa zamphongo za hydraulic zomwe zimapanga mphamvu zambiri m'dera la mapaundi 3000 pa inchi imodzi.
Kuwonjezera fyuluta mbale kusefera sing'anga, ndi kukula fyuluta keke timapitiriza kuchotsa particles zabwino mu slurry. Yankho kubwera kudzera fyuluta atolankhani madzi bibs, otchedwa filtrate, adzakhala pure.The kusefera akhoza chatsanulidwa kutali kuti atayike bwino, kapena akhoza kusungidwa mu thanki madzi zobwezerezedwanso ntchito. Pamapeto pa kusefera, keke yolimba ya fyuluta imatha kuchotsedwa. Njira yonse yosefera nthawi zambiri imayendetsedwa ndi zamagetsi kuti izipanga zokha kapena zodziwikiratu.
